President Obama is seeking $83.4 billion to fund the wars in Iraq and Afghanistan, a congressional aid said Thursday.

It is expected that some kind of emergency funds will also be included for floods in North Dakota and other unexpected disasters from weather-related events.

Once the bill approved by congress, the total money for U.S. operations in Iraq and Afghanistan will mount to almost $1 trillion since September 11, 2001.

Tom Gavin, budget office spokesman, said the White House will send an official request to Congress this afternoon.

Obama announced plans in February to withdraw U.S. troops from Iraq within 19 month.
